Large scale Metrology challenges at CERN
The European Organization for Nuclear Research, known as CERN, builds the largest tools on Earth – colliders and detectors – to study the smallest constituents of matter. Its flagship is the Large Hadron Collider (LHC), a 27 km long collider, consisting of more than 1600 supra-conducting magnets operating at 2 K and accelerating cavities to enable particle beams circulate and collide in four large detectors. The geodetic metrology group at CERN provides metrology and alignment for components installed in the accelerators, their beam transfer lines and the physics experiments throughout the CERN complex. It also performs R&D related to these tasks for upgrades of existing machines and for future accelerator and experimental projects. In this presentation, I will first briefly review the instrumentation and methods developed for the LHC. I will then present the new alignment systems under preparation for the LHC upgrade, based on Frequency Scanning Interferometry, before concluding on the R&D performed on the Future Circular Collider study, to prepare the post LHC era.

Time: 11:25-11:50
The speaker is Davina Di Cara, Senior Electric Propulsion Engineer (TEC-MPE)
Electric Propulsion: an enabling technology for space science, exploration, communication, remote sensing and space transportation.
The presentation outlines the European Space Agency’s (ESA) advancements in Electric Propulsion technology, aimed at enhancing space competitiveness and enabling new applications. ESA’s ongoing developments support various missions, including telecommunication in GEO/LEO/MEO, science, remote sensing, navigation, space awareness, space logistics, and space exploration. ESA collaborates with the European Commission, National Space Agencies, industry, research centres, and academia to mature this technology through ground qualification and in-orbit demonstration. The goal is to increase reliability, competitiveness, industrialization, mass production, and European independence. Additionally, ESA is pursuing innovative Electric Propulsion technologies to enable new missions or applications and to respond to future space exploration and transportation needs.
The presentation summarizes ESA’s ongoing activities, achievements, readiness status, technology gaps, market perspectives, trends, and opportunities.
Davina graduated in Aerospace Engineering from Politecnico di Torino (IT) in 2003 and joined the propulsion team of the European Space Agency in 2004. She is a senior Electric Propulsion Engineer with over 20 years of experience in ESA projects support and R&D management. She is responsible for the ESA Roadmap on Electric Propulsion and CubeSat Propulsion and serves as the Deputy Manager of the ESA Propulsion Laboratory.
